V6065. A non-serializable class should not be serialized.

Dec. 14, 2018

The analyzer has detected serialization of an object that lacks the implementation of the java.io.Serializable interface. For correct serialization and deserialization of an object, make sure its class has this interface implemented.

If it comes to serializing the 'dog' object, a java.io.NotSerializableException will be thrown. To ensure correct execution of this code, the java.io.Serializable interface needs to be implemented in the 'Dog' class.
